Abstract

Es wird eine Brennkraftmaschine insbesondere für ein Kraftfahrzeug beschrieben. Bei der Brennkraftmaschine wird Kraftstoff von einer Zumesseinheit (15) zu einer Hochdruckpumpe (16) zugeführt. Weiterhin wird Kraftstoff von der Hochdruckpumpe (16) in einen Druckspeicher (17) gefördert. Der von der Zumesseinheit (15) zu der Hochdruckpumpe (16) zugeführte Kraftstoff ist entsprechend der maximalen Förderleistung der Hochdruckpumpe (16) begrenzt. Durch ein Steuergerät (20) wird bei einer Verminderung des Drucks in dem Druckspeicher (17) die Begrenzung des von der Zumesseinheit (15) zugeführten Kraftstoffs überschritten. Weiterhin wird bei einem nachfolgenden Anstieg des Drucks in dem Druckspeicher (17) auf einen Fehler im Bereich vor der Hochdruckpumpe (16) geschlossen.

Figure imgaf001
An internal combustion engine is described, in particular for a motor vehicle. In the internal combustion engine, fuel is supplied from a metering unit (15) to a high-pressure pump (16). Furthermore, fuel from the high-pressure pump (16) in a pressure accumulator (17) is promoted. The fuel supplied by the metering unit (15) to the high-pressure pump (16) is limited in accordance with the maximum delivery rate of the high-pressure pump (16). By a control unit (20), the limitation of the fuel supplied from the metering unit (15) is exceeded when the pressure in the pressure accumulator (17) is reduced. Furthermore, in the event of a subsequent increase in the pressure in the pressure accumulator (17), an error in the region upstream of the high-pressure pump (16) is concluded.
